🔢 CR Increment Float

Documentation

• Class name: CR Increment Float
• Category: 🧩 Comfyroll Studio/🎥 Animation/🔢 Interpolate
• Output node: True

The CR_IncrementFloat node is designed to incrementally adjust floating-point values, facilitating the creation of sequences or gradients of numbers. This node is particularly useful in scenarios where gradual changes or interpolations are required.

Input types

Required

• start_value
  • Specifies the initial value from which the incrementation starts, setting the baseline for the sequence generation.
  • Comfy dtype: FLOAT
  • Python dtype: float
• step
  • Determines the increment size for each step, directly influencing the pace and scale of the sequence progression.
  • Comfy dtype: FLOAT
  • Python dtype: float
• start_frame
  • Defines the starting frame for the incrementation process, marking the point at which the sequence begins.
  • Comfy dtype: INT
  • Python dtype: int
• frame_duration
  • Specifies the duration in frames for each increment step, affecting the timing and pacing of the sequence.
  • Comfy dtype: INT
  • Python dtype: int
• current_frame
  • Indicates the current frame in the sequence, used to calculate the current value based on the starting point and step size.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• FLOAT
  • Comfy dtype: FLOAT
  • Outputs the current incremented value, reflecting the progression of the sequence.
  • Python dtype: float
• show_help
  • Comfy dtype: STRING
  • Provides additional information or guidance related to the node's operation.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
